The Supreme Court of India is the highest judicial forum and final court of appeal under the Constitution of India, the highest constitutional court, with the power of constitutional review. Consisting of the Chief Justice of India and 30 other judges, it has extensive powers in the form of original, appellate and advisory jurisdictions. As the final court of appeal of the country, it takes up appeals primarily against verdicts of the High Courts of various states of the Union and other courts and tribunals. It safeguards fundamental rights of citizens and settles disputes between various governments in the country. As an advisory court, it hears matters which may specifically be referred to it under the Constitution by the President of India. It also may take cognizance of matters on its own, without anyone drawing its attention to them. The law declared by the Supreme Court becomes binding on all courts within India.
